917 Polyurethane Adhesive Assembly And Bonding Of Windshield Glass Of Engineering Machinery Cars, Ships

Huitian®917 polyurethane adhesiveis a one-component, black, low-viscosity, high-strength, low-odor polyurethane adhesive. After curing the adhesive layer is elastomeric, with good resistance to changes in temperature and stress. The product is suitable for manual gluing.Typical TechnicalData(Real values may have deviations)ColorBlackDensity1.35 g/cm3Solid content, ISO78799.5%Curing rateSee Figure 1Tensile strength, ISO 5274.0 MPaElongation at break, ISO 37400%Shear strength, ISO 45872.0 MPaTemperature resistance-40°C~90°CShort-term working temperature (max. 1h)120°CChemical ResistanceHuitian®917is generally resistant to fresh water, seawater, weak acids and weak alkali solutions, but is not resistant to solvents such as organic acids, ethanol, concentrated acids and concentrated alkalis.Directionsfor UseHuitian®917is suitable for assembly and bonding of windshield glass of engineering machinery cabs, cars, ships, etc., as well as bonding and sealing of some metal structural parts.Before using the product, it is necessary to read the Material Safety Data Sheet for information on precautions and safety recommendations. Before using 917 on materials prone to stress cracking, please consult with the material supplier and perform substrate testing for verification; 917 is intended for experienced and professional users only. Tests must be conducted with actual substrates and application conditions before using the product, so as to ensure good adhesion to and compatibility with the material.Directionsfor CuringHuitian®917is a moisture-curing one-component polyurethane adhesive. Changes in temperature and humidity will affect its curing rate; the lower the temperature, the slower its curing rate.Application MethodSurface TreatmentThe substrate to be bonded must be dry and free of oil, dust, grease, and other contaminants. Thoroughly clean the new glass and body paint coat with 8902, and check whether the bonding material is intact and free of any damage. If new or changed substrates are involved, please contact Huitian for verification to ensure reliable bonding.Primer ApplicationApply primer to the cleaned substrate surface with a primer applicator. Start gluing after the primer evaporates and dries. Before application, a primer agent suitable for the actual substrate and application conditions should be selected according to Huitian’s primer program. Then apply the primer according to the primer application requirements.GluingIt is recommended to glue with equipment (such as pneumatic and electric glue guns or equipment with pumps). In order to ensure a uniform thickness of the bonding layer, it is recommended to form a triangular adhesive shape (as shown in Figure 2).The optimal operating environment conditions are temperature 20~30°C, 50%~70%RH; note that the viscosity of the product will increase at low temperatures. The open time will be significantly shortened under high temperatures and high humidity; if the glue is already tack-free, please do not conduct assembly and bonding.During gluing and curing, avoid contact with chemicals containing hydroxyl groups, amino groups, etc., which can cause polyurethane adhesive to not cure or incompletely cure.StorageThe unused adhesive should be immediately sealed for storage. When used again, if there is a small amount of crust on the seal, just remove it, which will not affect the normal use of the product. During storage, a small amount of crust may appear at the opening, which can be removed for normal use and will not affect the performance of the product.Cleaningand RemovalUncured 917 can be cleaned and removed with special cleaners or other suitable solvents and tools of Huitian. Once cured, it can only be removed mechanically. If the skin on, for example, hands is contaminated, clean up immediately with a towel dipped in ethanol or a suitable industrial hand sanitizer. To avoid burns, do not use solvents on the skin.Storage & TransportationRecommended transportation environmentOptimal environment: 5~25°C, <70%RH; avoid sunshine, rain, humidity, impact, and extrusion of packing.Recommended storage temperature5~25°CStorage environmentCool, dryShelf life9 monthsIf the storage environment temperature is exceeded, there may be a risk of shortened shelf life. (Shelf life is less than 9 months at a storage temperature of 25~35°C, and less than 6 months at a storage temperature of 35~40°C)Packing Specification300 ml/cartridge; 400 ml/cartridgeCautionsKeep away from children for storage.If the eyes are accidentally exposed to the product, rinse immediately with water, and seek medical attention.It is recommended to use the product in a well-ventilated place.Please consult the MSDS of the product for safety information.Waste DisposalIf not polluted by other substances, the waste can be stacked in landfills in principle and will not pollute water quality. Since the product can be burned, the waste can be disposed of in a waste incineration plant. Undoubtedly, it is necessary to abide by the environmental regulations of the local government.Health and Safety InformationBefore operating this product, it is necessary to get familiar with its hazards, proper use and disposal, and other relevant information.
